A seven-month-old girl was apparently abandoned Monday on a subway platform at Columbus Circle. Witnesses claim seeing a woman walk the child in its stroller off a northbound 1 train, leave the stroller and the child on the platform, and then turn around and get back on the train.

According to the New York Times, a woman discovered the child and stayed with her for 20 minutes before alerting authorities and that the child was taken to Mount Sinai Roosevelt by police as a "precautionary measure." From CBS New York:

Police said there were no apparent signs of trauma. The baby had a bandage on her hand and a slight rash, but was otherwise unhurt, sources said.

The child will be placed in custody of the city's Administration for Children's Services until her identity is established. There was no identification with her, sources said.

Authorities said it's unclear whether the woman intentionally pushed the stroller from the subway car. Police are looking for the woman, who they described as black and in her 20s or 30s.
